Fuel metering control method for turbocharged IC engine, fuel injection has replacement main control value provided when leak is detected in engine air intake

摘要

The control method uses a measuring device (1) for providing a main control value from the air quantity in the air intake (2) and a control device (3) for calculating the cylinder filling. A replacement main control value can be provided upon detection of a leak (8) in the air intake, via pressure monitoring, with the control device generating an undelayed fault signal and a delayed fault signal. An Independent claim for a control device for calculating the cylinder filling for a turbocharged IC engine is also included.
